A Flyball race sees two teams of four dogs each, racing side-by-side over a 51 foot long course. There are different tournament formats but each format involves racing between two teams at a time. Within a team, each dog must run over the jumps, trigger a Flyball box releasing a ball, retrieve the ball and then return over the jumps. The next dog is released, in relay fashion, to run the course but can't cross the start line until the previous dog has returned over the finish line. The first team to have all 4 dogs finish the course without error wins.
